UNITED STATES PATENT OFFICE.

GUSTAV KAISER, OF TROSSINGER, GERMANY.

MOUTH-HARMONICA.

SPECIFICATION forming part of Letters Patent No. 516,096, dated March 6,1894. Application led November 10, 1893. Serial No. 490.598. (No model.)

To all whom, it may concern.-

Be it known that I, GUSTAV KAISER, nierchant, of Trossinger, German y,have invented a new and useful Improvement in Mouth-Harmonicas, of whichthe following is a specification.

The object of the present invention is to provide a covering formouth-harmonicas, so formed, that the same will serve also as a casingadapted to be closed, and from which the instrument will automaticallyemerge in a definite position, as soon as the coverings which are hingedtogether on one longitudinal side are opened at the other side.Thelocking of the casing is effected by providingthe harmonica with twostuds or pins, secured to the base-piece, which are guided in slots inthe side-walls of the covering, by which studs the harmonica is pushedbach, thereby allowing the coverings to be automatically closed.

In the drawings- Figure l represents a plan of a mouth-harmonicaembodying my invention; Fig. 2 an end elevation, and Fig. 3 a frontelevation of the same, the covering being closed; Fig. 4 a similar view,the covering being open; Fig. 5 a sectional plan, and Fig. 6 atransverse section ot the same, on line Z-Z, Fig. 5.

A is the base-piece, upon which thev reedplates, B, are secured in theusual manner. The covering iiaps or sections, C, C', are distinguishedfrom those coverings hitherto ernployed in not being attached to thereedplates or the base-piece, but being extended at their rear portionsand hinged together at the end of the extensions, while the alsoextended front portions of the covering flaps, C, C', which completelycover the blow-holes, may be spread open, whereby the edge of theharmonica containing the blow holes is exposed, and is thrust forwardsufficiently to be used, by a spring, D, interposed between the rear ofthe covering or casing and the basepiece. To limit the advance of theinstrument, studs, d, secured to the base-piece, A, and guided in slots,c, of the end walls of the casing, O, are provided, The covering flaps,C, C', are automatically closed by a helical spring, d, arranged on thehinge-pivot and whose ends are attached one to each of the coveringiiaps. This spring also forces the front lips, c', of the coveringflaps, C, C', into the grooves or notches, b on the reed-plates, B,thereby forming a close joint between thc covering flaps and the saidreed-plates.

Vhat I claim, and desire to secure by Letters Patent, is-

l. The combination, with a mouth-harmonica, of two hinged covering flapsattached to the body oi the harmonica and hinged together at the rear oftheharmonica,substantially as set forth.

2. The combination, with a mouth-harmonica, of two covering flapssecured together in the rear of the harmonica by a spring-hinge, andattached to the body of the harmonica substantially as set forth.

3. The combination, with a mouth-harmonica provided with studs in itsends, of two covering iiaps secured together in the rear of theharmonica by a spring hinge, and slots in the covering in which thestuds are guided, substantially as set Jforth.

et. The combination, with a mouth-harmonica, ot' two hinged coveringflaps, hinged in the rear of the harmonica, and a spring interposedbetween the rear of the flaps and the harmonica, to automatically thrustthe harmonica forward when the covering is opened, substantially as setforth.

5. The combination of the following parts: a mouth-harmonica providedwith studs in its ends, covering flaps provided with slots for guidingthe studs, and a spring interposed between the harmonica and the rearot' the covering, whereby the harmonica is automatically thrust t'orwardto a limited extent, when the fronts ot' the covering Iiaps are opened,and the covering is automatically closed upon pushing the harmonica backinto the covering, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

GUSTAV KAISER.
